I would like start to share pictures and questions about the restoration of my 1952 Farmall Cub.I have an issue with the pto shaft, the pto was very worn so i take it to a person who fill the pto with metal and shape it to look like a new one, but the guy didn't realize to leave a little gap where the bearing retainer goes, can somebody give my the measures of the pto? i need to know how wide is the pto where the bearing goes and where the retainer goes, and the length from one point to the bearing retainer gap.Thank you very much! Tomorrow morning i will upload pictures an a video of the engine running!

I believe if the lip that the bearing seats up against is still in place, you can measure the width of the bearing to determine where the retainer groove should be to hold the bearing in place. Does this make sense?(photo courtesy of Ole Corky)

Thank you Raymond, i disassemble the pto and found that the lip where the bearing seats is actually the original place i guess, i just will have to make a new groove against the bearing so it won't move again. Do you know if i can install the pto with the shifter clutch installed on the pto? because is not easy to do it to engage the shifter lever on the groove of the clutch.Thank again.

Yes it will fit back in complete.Remove the oil fill plug on top the trans and with a light you can see down through the hole to this area where the clutch fits the lever groove....Removing the little pto lever guard on top of the trans will allow you more movement for the work area inside.

When positioning the PTO assembly up to the back of the transmission, make sure that the shaft engages the pilot Bushing on the back of the transmission shaft while the PTP lever engages the groove on the shift collar. It's a bit tricky, but as Yogie mentioned, remove the fill plug to help you see what's going on inside.

Here are some pictures of how look the place where i am starting the slow process of put all the pieces together, is not easy but is very nice job to do.I had already rebuild the engine in a shop, all the parts i brought them from USA (piston, rings, new crankshaft, valves, gasket) and many other parts to (lights, rods, ignition tune up kit, exhaust, etc..) There are only a few Cub's in Argentina. The engine runs really good I'm uploading a video to youtube.com to show you guys.i am struggling to get some tires to the tractor, so far i couldn't find tires, there is no any in Arg.

New engine waiting to run, i will assemble the engine with some other parts and paint all together!

Most of the parts are already painted, this look like a puzzle jaja.

Here is the video, i forgot to take off the cover of my camera, is an acuatic camera so at 2:30 seconds the sound is better because i take it off.Is impossible to import tires to Argentina, right now with our president is a law to substitute all the importation's, we can not even buy tires for the tractors that we use to plant.

I don't mean to sound like the safety police or a nervous ninny, but this is not a good way to run an engine for several reasons. I know that you are happy to have the engine back from a rebuild, and it does sound good, but bad things can happen quick under the conditions in the video.It is perfectly ok to run an engine off the tractor, but it needs to be secured in some manner, preferably on an engine stand. One miss to throw it off balance and the engine will fall off the table on the floor. I know the engine wasn't run for very long, but fresh cool water needs to be supplied. Connect the lower water inlet to a faucet and water hose, and turn the water on just enough so that it has at least a trickle out the upper water outlet. The carb appears new, and the throttle shaft felt is probably tight against the shaft, but without it connected to the governor, a runaway throttle can happen as the butterfly can quickly open to full by itself before you can get your hand on it to stop it. I've had it happen to me while I was on the other side of the engine. Luckily I was able to quickly hit the ignition switch before something bad happened!I'm not trying to rain on your parade, I just don't want to see your hard work ruined. Keep us posted on your progress, and if there is anything we can do to help, please let us know!
